General Information

Term

split protein splicing tag

ID (Ontology)

FBcv:0009054 (FlyBase CV)

Definition

Sequence that forms part of the protein product encoded by a transgenic locus or modified endogenous locus and that can catalyze protein splicing when brought together with a complementary split protein splicing tag in vivo. Typically used to join two separate protein sequences by trans-splicing; in this case the two separate protein sequences are each initially tagged with one half of a pair of complementary split protein splicing tags. Alternatively, if both halves of a pair of complementary split protein splicing tags are used to tag each end of a single protein sequence, they can be used to generate a cyclized protein molecule.
